## What the aircraft actually flies over

From Sydney the path crosses 1,956 km of open water, then New Zealand.

The furthest the great circle gets from the equator is 43.5°S, 100% of the way along.

Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree.

Leaving Sydney the aircraft points south-east (126°); it arrives into Christchurch heading south-east (113°). That is 13° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.

One economy seat on it is about 315 kg of CO₂e each way, counting non-CO₂ warming.
